gravitation.l At the base of this channel, I locate my improved typeejector, which is arranged to shove the type from the vertical Y channellaterally onto a suitable type chase.

The type chase may readilybe a grooved segmentA such as is commonly usedon the innltigraph. The segment is, ot' course, preferably'removablefrom the type ejector mechanisni so that it may readily be installedonthe multigraph for printing purposes. The arrangement of my type ejectoris such that it will discharge or eject type from the receiving channelat a much higher rate of speed than `is possible for the operator toVselect individual type, with the usual keyboard i Vis arranged to shovethe type laterally from the receivingchannel 11 onto a grooved segmentor chase 14. The individual type may be supplied to a "receiving channel11, by a keyboard Operated composing `machine, (not channel 11, which,at its lower end, is supported in a bracket 15, lie one ontop o1 the`preferred form of my inventionlinounted on j sliown)." The type, asthey idescend in the j,

Qis a fragmentaryvertical section through 80 other, coming" to rest-uponan ejector or plunger bar 1h. The plunger 16 is mounted lforreciprccation in a horizontally extending channelv 18, in a base block17.

The 'channel 18 is arranged in a plane norma] to the plane of thereceiving channel 11.

Hence, `as the plunger moves to a point to the lett of the channel 11,the type A', which rests on the upper face of the plunger V(Fig.

channel `18.` Then, upon the forward move- 4-ment oftheplunger to theright-hand. position, as shown in Fig, the typeA willbe shoved alongthechannel 1S into a suitable channel 19 of the type chase 14. Thechannels 19fare arranged in the usual manner so that they maybe indexedandbrought into alignnient `with the channellS, as desired.

The Operation is such that for each back 4eo V13), will drop onto thebottom wall of the and forth movement of the plunger 16, the bottommosttype in the channel 11 is shoved onto the chase. This operation iscommon to the action of many type ejectors. However, until recently suchtype ejectors have been for the most part operated in a timedrelationship to the operation of the composing machine.

Recently, keyboard controlled composing machines have been built whichare operated with comparatively little power and at a very rapid rate ofsneed, and it has become desirable to provide an 'tor mechanism whichwill rapidly eject the type from the receiving channel, so that theejection will normally take place at a higher rate of speed than it ispossible for an operator to operate the keys of the type set-tingmachine, thereby preventing the type receiving channel from becomingunduly filled, which would cause disadvantageous results. 1t is evidentthat with such composing machine, the type ejector must be constructedto eject type both when the channel contains many type or when a type isdropped into the empty receiving channel wit-hout any regard. whatsoeverto the posit-ion of the type ejector plunger. This, of course, createsgreat possibilities for breakage and jamming of the type in the deliverychannel.

To handle the type so as to avoid the possibility of breakage at theejection region, I provide the controlling mechanisms now to bedescribed. l arrange my type ejector so that the type, as they descendthrough the channel 11, are stopped therein by a suitable mechanism andthen permitted todrop one at a time before the withdrawn ejector bar 16,at a predetermined point in the travel of the bar. rlhis, therefore,prevents the type from being breken due to the differences between thetiming of the operations of the type setting machine and the typeejector. To this end, l mount a plunger` 20 in the rear or leftf handface of wall of the receiving channel 11, and so arrange this plungerthat it may be reciprocated by a bell crank 21, pivoted at 22 to theframe of the ejector, and resiliently urged into a position to cause theplunger to be thrust into the channel 11 by a tension spring 23, securedat one end to an arm 24 of the bell crank 21, and at the other end to asuitable frame member 25. This arrangement is such that the plunger 20is normally in a position projecting into the channel 11 to prevent typelodgedl therein from descending` into the channel 18.

To permit the type to fall in timed relationship relative to the plunger16, I prefer to provide the plungerl with a pintor roller 27, which isarranged to eoact with a cam surface 28 on a rearly extending arm 29 ofthe bell crank 21. l/Vhen the plunger 16 is in its extreme right-handposition (Fig. 3), the plunger 2O will be withdrawn from the channelpermitting the type therein to descend, the bottommost type A descendingto a position where it rests on the top surface of the plunger 16.

Thereafter, as the ejector bar or plunger 16 is drawn to the left, fromthe position shown in Fig. 3, to that shown in Fig. 4, the plunger :2Ois released, thereby permitting the spring 23 to force it against thesecond type from the bottom (namely, the type A on Fig. 3) and retain itin the channel 11, thereby permitting` the bottom type A to descend bygravity into a position resting on top of the plunger 16. As soon as theplunger 16 is completely withdrawn, the type A will descend bygravityand rest before the plunger in the channel 18. Thereafter, the plungeris forced towards the right, ej ecting the type A out of the channel 18and onto the type chase.

Due to the comparatively small size of the type `and their irregularshape, they must be guided during the descending movement from thechannel 11 into the channel 18. To this end, I so arrange the plunger16-that it is withdrawn only a. comparatively slight distance to theleft of the channel 11, and thereby enable the forward end thereof toform, when in the withdrawn position, a continuation of the rear wall4;() of the ch annel 11. At the right-hand end or outer face of thechannel, I provide a guard in the way of a curved bar 30, having abeveled nose 31, arranged to operate in a slot 32 in the channel 11. Thearrangementof this bar is such that when the plunger is in its extremeright or e1;- tended position, the nose of the bar extends into' thechannel adjacent the right-hand face of the type A, and as this typedescends, due to the rearward movement of the bar, hereto` foreexplained, the nose 31 of the lever 30, follows the type downwardlyuntil it rests iu the channel 16. This bar therefore forms acontinuation of the front wall 41 of the channel 11, and, together withthe front face of the plunger' 1G, prevents the type from turning ortwisting in the channel 11, or gu 'deway 18, due to the withdrawing ofthe type supporting surface of the plunger. As the ejector bar comesforward, the bar or guard 30 is raised, thereby permitting the type tobe ejected.

The guard 30 comprises a curved lever 33, pivoted at 34 tothe frame ofthe ejector, and

normally retained in the uppermost position (shown in Fig. 3) by atension spring 35,. having one end thereof secured to the rearwardly Iextending arm 36 of the guard, and the other roller v53 arranged to bedrawnjinto contact to raise the guard neit/327e by providing arestrictedchannel for the type. Likewise, Whenthe plunger moves forwardtoeject a type, thefpin 2,7 moves' awayfrom the cam surface 38,permitting 4the spring 35 and clear the path of the plunger 16. L l j pTo operate the type'ejector', the plunger 16 is reciprocated.` As shown`in Fig, l, a lever "50, pivoted at 451 to the framelO, has a "pin andslot connection 52 with the plunger 16. On its lower end, the lever.`5() carries a cam `with acam 54 by a suitable tension spring LVl55`,"one end of which is secured toa :trame pin i` 56 and the otherto'tlieflower edge of the lever 50, as at517. The cam Ms rigidly securedto a shaft 58, journalled. in the frame 10. A

` l pulley 59is rigidly secured to the shaft 58 and is driven, throughthe medium'of a belt or chain Glfi'roma `pulley 62, 'which is rigidlysecured totheQarinature shaft 63 of a suitable motor (ill.
